FLANGE non BULL-WHEEL 'rs.

To all whom it may concern:

B it known that GEORGE F. BELL, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, has invented certain new and useful Improvements in Flan es for Bull-Wheel Shafts, of which the fo lowing is a specification.

This invention relates to a novel construction of flanges such as are utilized in connection with bull wheel shafts of oil well drilling machinery for guiding1 and retaining in desired position a cable t rough which the drilling tools are mani ulated.

Heretofore flanges o the type in question hav been constructed in such a manner that the cable in certain positions is bent or kinked by engagement with'the bolts which retain the flange sections together on the shaft. Obviously a cable bent as indicated will necessaril be out of alinement and quickly wear y contact with the casing with the result that the cable portion so injured must be discarded resulting not only in unnecessary expense but in a waste of time and labor.

By the present invention I have constructed a flange which will at all times keep the cable free from engagement with the bolts and will permit the desired movement of the cable, the flange itself being of unusual strength and durabilitly.

More specifically I ave provided a sectional metal flange with-a guideway for carrying the cable direct from the shaft to either the reserve or working coil, such 7 guideway being formed substantially as an integral element of one of the flange sections and comprising an arc-shaped groove section adjacent the upper edge of the upper sectionand extending diagonally of the transverse axis of the shaft on which it is mounted, to opposite sides of said flange, and two vertical guideways which merge at their upper ends into the terminals of said arcshaped groove and at their lower ends into tapered guides formed by inclined wall portionsof the hub of the lower flange section.

Also I have included liners to permit the use of the present invention on either wooden or steelshafts, these liners being shaped to conform to the shape of the flange hub portions and to co-operate with the cable guideway.

Other f i .-.s of construction and advantages derived from the present arran ement will more clearly hereinafter appear y reference to the accompanying drawings formmg a part of this specification and wherein like numerals of reference designate corresponding parts throughout the several views, in which: 4 Figure 1 is a side elevation showin the flange in position on the bull wheel sha Figure 2 is a similar view enlarged showing only a portion of the shaft.

Figure 3 is a top plan view showing the flange in position.

Figure 4 is a front elevation.

Figure 5 is a plan view of the lower half of the flange.

Figure 6 is a plan view showing the secand Figure 7 is a similar view of the lower flange section.

The resent invention is shown arranged on the ull wheel shaft A which may be of either wood or steel as will more clearly appear, and comprises upper flange section B and lower section 0. Both of these sections are of cast metal and are provided with hub sections 6 and a and radiating semi-circular flange portions 6' and 0 respectively. A series of webs D are utilized to strengthen the flange portions 1) and c and to effect a fixed relationship between such flange portions and the hub portions 7) and 0. These rein forcing webs are arranged in such a manner as to secure the best possible strength of the entire unit and it will be seen from an examination of the drawing that various short web portions connect the elements of the upper and lower flanges. Suitable bolts E secure the flange sections B and C together and extend through tubular enlarged portions 6 provided therefor on opposite sides of the hubs.

Referring now to the substance of the present idea attention is first directed to the path of travel of the cable a illustrated more clearly in Figures 2 and 3; From these figures it will be seen that the cable a is carried to the opposite sides of the flange for its diflerent functions by means of novel guideways or grooves. These 1gi'uideways include in the upper section B t e arc-sha ed section F having a radius substantially i entical with the radius of the shaft A but with an axis spaced above the circumference of the latter, and the vertical parallel guidetion of liner used in the upper half of flange.

we. s and These guideways f and 'f' are fdrmed in the opposite faces of the flange section B and merge into the arcsha ed oove F which latter necessarily exten s diagonally to the transverse axis of the shaft A. An examination of these grooves or guide-ways will disclose wall sections which partially enclose same to asslst in retaining the cable in the desired path of travel.

At op osite ends and on opposite sides 9 and g t e hub portion a of the lower flange section G is cut away at such angles as may be necessary to permit access of the cable a to the vertical ideways f and and proper feeding 0 such cable to the shaft A.

In Figures 6 and 7 I have illustrated liners H and J. These liners are necessary in instances where a steel bull wheel and shaft is used inasmuch as such steel shafts measure 16" outer diameter to 18" outer diameter of the wooden shafts; Suitable keys and retainin lugs are provided to fix these liners in sition.

e liner H for the upper hub section B has cut away portions at diametrically opposite points and h where the vertical guideways f and f terminate and the lower liner J is necessarily cut away at 7' and j to correspond to thecontour of the hub portion to which it is ap lied.

The application an use of the present invention will be apparent to one skilled in the'art. The particular construction and arran ement of the guide grooves providing for the feeding and manipulation of the cable to opposite sides of the flange as may be desired, the cable being at all times free from binding or crimping due to engagement with irregular surfaces.

What I claim as new and useful and desire to secure by Letters Patent, is

1. In combination, a shaft, a cable to be coiled on said shaft and a flange mounted on the shaft and formed with a guideway for said cable, said guideway extending from one side of said flange to the other and terminating at points adjacent said shaft.

2. A flange for a bull wheel shaft including upper and lower sections, one of said sections being formed with an arc-shaped groove communicating with. opposite sides 'of said flange, and a guideway communicating with said groove at each end thereof, each of said guideways terminating at a point adjacent said shaft. I

3. A flange for a bull wheel shaft including upper and lower sections, means for 1,4es,aes

securing said sections together, and an arcsha ed groove in said flange spaced between sal securing means communicating with oppo s1te sides of said flange, said groove terminating at diametrically opposite points on said shaft.

4. In a device of the class described including in combination a shaft, a cable, a flange and guide means for said cable formed inte ral with said flange and includlng a curve groove formed in one side of sa1d flange an extending from one side'of said flange to the other and guideways arranged on opposite faces of said flange and communicating with said curved groove.

5. A flange for a bull wheel including upper and lower sections and a hub, a groove formed adjacent the upper eriphery of said up 'er section and exten mg from one side 0 said section to the other, and grooves formed in the opposite faces of said upper section communicating with the first mentioned groove and terminatin adjacent said hub, and guide walls formed at opposite sides of said hub and communicating with said grooves.

6. In a device of the class described including in combination, a shaft, a cable on said shaft, a flange for said shaft including upper and lower sections and a hub portion, a curved groove formed adjacent the upper periphery of said up er section and arranged diagonally to t e transverse axis of said shaft to communicate with the opposite faces of flange section, a vertical parallel guide way formed in each of the opposite faces of said upper flange section and merging into said curved groove at their upper ends, the lower ends of said vertical guideways terminating at points adjacent said shaft, and walls formed in the hub portion of the lower flange section to guide said cable to said vertical guide ways.

7. In a device of the class described including in combination, a shaft, a cable, and

a guide flange mounted on said shaft formed with a transverse cable guideway extending from a point adjacent said shaft on one side of said flange to a point adjacent said shafton the opposite side of said flange.

8. In a device of the class described, a shaft, a cable, and a flange mounted on said shaft having cable guideways in its opposite faces extending from a point adjacent said shaft and communicating with a connecting curved groove formed at. a point spaced from the outer face of said shaft.

In testimony whereof I afiix my signature.

GEORGE FRANCIS BELL.
